Boot in Recovery Mode [Don't skip this steps are relly required to get new partition layout working as well]

A1 owners (256mb ram) necessarily require a SWAP partition, an EXT partition is also suggested for both liquid models

if you don't have one create it:

choose Advanced option in recovery menu

select Partition SD Card

choose your prefercences and wait for partion process end

Wipe ALL [IMPORTANT]

select wipe data/factory reset

select wipe cache partition

Rom Flash

Download cm9 archive for your device and push it to your sdcard

Select Install zip from sdcard

Choose cm9 archive and wait for installation end

Select reboot system now

ENJOY your CM9

First boot can take a while up to 5mins.

Advices:

Enable SWAP: Install a2sd script it's an easy way to get it working.

Data not working:open with root explorer your /system/build.prop file you should find a line like this:

ro.telephony.ril.v3[/font]=skipbrokendatacall,signalstrength,datacall

edit it, removing datacall parameter. so it should be like this:

ro.telephony.ril.v3=skipbrokendatacall,signalstrength

save your build.prop and reboot.

Mass Storage in Recovery Mode: Best way to use it, is using adb. Mount your sdcard (mounts and storage->mount /sdcard).

adb push SOMEFILE /sdcard/

BootLoop on first Boot: It's a common problem on a1 (256mb ram) device. To solve just be sure you've enabled SWAP. Boot rom with opengl enabled requires a big amount of ram. After boot you should have about 50mb free ram. So it's really needed only to boot your device.

Differences between LiquidA1 and LiquidE roms: We are sorry to use two different roms atm.. But a1 needs more tweaks to run ICS, about dalvik vm and other stuff, we will merge two project that maybe in next release patching installer script. Anyway rom is pretty the same, kernel is the same (for now), so don't worry about that.

Please remember it's an under-development rom, so it needs still a lot of work to be really ready for a daily usage, and with all hardware working. We're working hard to get that.And please don't report bugs about already known not working stuffs.

Tips:

A1 (256mb) random hangs fix [thxRomzesRover]:

Quote

Turn on compcache (18%)
Tick "Allow purging of assets"

Uninstall/Go back to older roms:

i think this should be clarified.

Liquid E (512mb ram) users can use this new recovery to flash older roms or restore nandroids.
